Which (metals or nonmetals) are most likely to give away electrons?

1 answer:

6 0

As mentioned above, the characteristic chemical property of a metal atom is to lose one or more of its electrons to form a positive ion. However, certain metals lose electrons much more readily than others. In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li).

Why do hotspots appear to move in relation to tectonic plates?

Vikentia [17]

Answer:The heat that fuels the hot spot comes from very deep in the planet. This heat causes the mantle in that region to melt. The molten magma rises up and breaks through the crust to form a volcano. While the hot spot stays in one place, rooted to its deep source of heat, the tectonic plate is slowly moving above it.

The “fatal flaw” in Rutherford’s model of the atom was the idea that if the electrons were ________.

Wittaler [7]

The correct option is A. Rutherford model of the atom consider an atom to be made up of a central nucleus with electrons orbiting around it. The nucleus is considered to be tiny, heavy and its positively charged while the electrons are negatively charged. The shortcoming of this model is that it was not able to explain how the positive nucleus was not able to attract the negative electrons and pull them inside the nucleus.

a gas witha bolume of 2.2 L at 140 kPa expands to fill a 4.4 L container. What is tje pressure in the new container ? the temp d

taurus [48]

By the use of the Boyle's law, the new pressure is 70 kPa.

The gas law enables us to calculate the parameters that has to do with gases.

In this case;

V1 = 2.2 L

P1 = 140 kPa

V2 = 4.4 L

P2 = ?

Using the Boyle's law;

P1V1 = P2V2

P1V1/V2 = P2

P2 = 140 kPa * 2.2 L/4.4 L

P2 = 70 kPa
